Wanpaku Ôji no Orochi Taiji

Wanpaku Ôji no Orochi Taiji (Japanese: わんぱく王子の大蛇退治 - literally "The Naughty Prince Slays the Giant Serpent") is an anime film produced by Toei Animation and released in Japan on March 24, 1963. English-dubbed versions were released under several titles, including The Little Prince and the Eight-Headed Dragon, Prince in Wonderland and Rainbow Bridge.

This is one of the few anime films to have music by famed composer Akira Ifukube. Ifukube was given more time to write his score for this film than most of the other films he had composed for. Some of this film's music was also featured in two episodes (including the first episode) of the anime series Mazinger Z.
